Giant rotating string of galaxies is 'probably the largest spinning object' in the known universe...

Astronomers have spotted what is likely the "largest spinning object" ever discovered, and its rotation could hold important clues about how galaxies develop.
The whirling structure, located 140 million light-years from Earth, is a long, threadlike string of gas that's about 5.5 million light-years long and 117,000 light-years wide — wider than our Milky Way galaxy. The cosmic filament has 14 hydrogen-rich galaxies linked to it in a chain, like charms on a bracelet. These galaxies were what gave away the filament's existence, the researchers explained in a paper published today (Dec. 3) in the journal the Monthly Notices of the Royal Astronomical Society.
